seemps.analysis.mesh.ChebyshevInterval

class seemps.analysis.mesh.ChebyshevInterval(start, stop, size, endpoints=False)

Irregular discretization between start and stop given by the zeros or extrema of a Chebyshev polynomial of order size or size-1 respectively. The nodes are affinely transformed from the canonical [-1, 1] interval to [start, stop]. If endpoints is set, returns the Chebyshev extrema, defined in the closed interval [a, b]. Else, returns the Chebyshev zeros defined in the open interval (start, stop).
